APPARATUS FOR MAKING WAX OR PARAEFINE PAPER.

SPECIFICATION forming part of Letters Patent No. 326,688, dated September 22, 1885.

(No model.)

To all whom, it may c0ncern:

Be it known that I, EDWARD G. Srnnxs, of the city of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Apparatus for Making \Vax or Paraffiue Paper, of which the following is a full, clear, and exact description.

This invention has for its object simplifying or improving the manufacture of waxed or other like paper for preservative and other uses. and to produce a superior article of the kind by laying the wax, &c., on both sides or surfaces of the paper evenly and of the same thickness, without thoroughly saturating the body of the paper, and to give the paper a fine, glossy finish. The wax or paraffine paper now in use is generally made by putting the wax, &c., on one side of the paper only, and by means of hot rollers remelting or rubbing the wax through to the opposite side, thereby causing a considerable waste of wax by saturating the body of the paper, whereas only a thin coating on the surface is necessary. One side of the paper also is often left insufficiently coated.

The invention consists in an apparatus of novel construction, and including special details and combinations of parts or devices for evenly distributing the wax, &c., over both sides of the paper with the advantages above stated, substantially as hereinafter described and claimed. Like means may also be used for waxing or waxing and polishing the pa per only on its one side, when so desired.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate cor responding parts in both the figures.

Figure 1 represents a sectional elevation of an apparatus, or so much of it as is necessary here to be shown, for making wax or paraffine paper embodying my invention; and Fig. 2, a view in elevation of a modification thereof.

Referring in the first instance to Fig. 1 of the drawings, A A are two tanks to hold the wax or paraffine, as the case may be. These tanks, which are arranged side by side at a suitable distance apart, are slotted on their front or adjacent sides, as at b b, and may be provided with spouts or hollow extensions at such points, said slotted parts or duets b being arranged one above the other and extending across the faces of the tanks. These passages or openings I) I) provide for the insertion of brushes B, which have an exposed projection at their outer ends, and may enter any desired distance within the tanks, and they also serve to admit of the use of a series of feed-regulating wedges, C, from within the tanks for controlling the supply of wax to the brushes. The wax in the tanks, which should stand at a proper level above the uppermost brush B, may be heated by steam-pipes D, or otherwise. In Fig. 2 four tanks are shownthat is, two pairs of tanks A A, each pair consist-ing of two tanks, one above the other,

and each tank only having a single brush, B; but the apparatus otherwise is generally the same,and the action in no way differs whether two or more tanks be used or each tank have one, two, or more brushes. may extend the full width of the front or facing sides of the tanks, and they completely fill the passages 1), extending about half an inch, more or less, beyond or outside of the same, and so that the brush or brushes of either one tank are out of line in an upward direction with the brush or brushes of the opposite tank, or occupy a slightly overlapping or underlapping position relatively thereto; and they, or the tanks which carry them, are furthermore arranged so that the brushes of the opposite tanks are intermediate of each other. Said brushes may be composed of hair or any other suitable material. The wedges C, which conform to the facial length of the passage 1), and are arranged to enter the inner ends thereof, either above orbeneath the back end portions of the brushes B, form or act as compressors to the brushes and as gates or valves to the passages 12, to regulate the flow of the fluid wax or coating material 8 to the brushes B. For this purpose said feed-regulating devices 0 are adjustable by means of screws E, extending through the backs of the tanks for the convenience of operation, and are drawn back or pushed forward,accordingly as it is required to give a free or limited supply of wax to the brushes B. By this means the supply of wax can be adjusted as desired, according to the use the paper is intended for; or the supply may be wholly shut off when required.

The brushes B G G are rotatable brushes, of which there may be two or more pairs, if desired, the same being composed of hair or any other suitable material, and between which the waxed paper is passed after it leaves the waxing-brushes B to give said paper a glossy finish. To this 7 end the brushes or glossing devices G are arself feeding or supplying waxingbrushes B B, and which, after being waxed or cooled,

is passed between the revolving polishingbrushes G G, and from thence wound on a take-up reel, as in other paper-making machinery.

In an apparatus constructed to operate as described not only is the melted wax laid evenly and automatically and of any desired thickness on both sides of the paper, without wasting the wax by forcing it into the body of the paper, but the waxing-brushes exert such a soft and gentle pressure as in no way to endanger the tearing or injuring of the paper, all harsh scraping being avoided, and the paper when it leaves the apparatus has a fine, glossy finish on both sides, either of which may be exposed or used with like efficiency.

When it is desired only to wax the paper on its one side, then the wax-holding tank or tanks carrying the projecting waxing-brushes 4 may be arranged to supply the wax to the paper on its one side only, as the paper is drawn over said brush or brushes, and only one polishing-brush for operation on the waxed side of the paper may be used.

Having thus described my invention, what I claim as new, and desire to secure by Let-- ters Patent, is

1. An apparatus, made substantially as shown and described, for waxing paper, consisting of a wax-holding tank, through the side of which projects a wax-supplying brush, op-' erated as set forth.

2. An apparatus for waxing paper, made substantially as shown and described, consisting of two or more wax-holding tanks having wax-supplying brushes projecting through their sides and adapted to cover with wax both sides of the paper web when drawn between the brushes as set forth.

3. In apparatus for making Wax or paraffine paper, the combination of two or more tanks for holding the melted wax or coatlng substance arranged side by side at a suitable distance apart and provided each with one ormore slots or passages in its side opposite to the adjacent side of the opposite tank and below the level of the material in the tank for distributing the wax or coating material over both sides of the paper as it is drawn between the tanks, said slots or passages being out of line with each other, substantially as specified.

4. In apparatus for making wax or paraffine paper, the combination, withthe tanks and their laterally-proj ecting waxing-brushes, of means, operating substantially as described, for regulating or shutting off the flow'of the material in the tanks to said brushes, substantially as specified.

5. In apparatus for making wax or paraffine paper, the combination, with devices for laying the coating material on the paper, of v one or more rotary polishing-brushes for glossing the waxed surface or surfaces of the paper after the wax or'coating material has set and cooled thereon, essentially as described.

6. The combination of the oppositely-arranged tanks A A, having slots or passages the laterally-projecting brushes B B, and the adjusting wedges O C, essentially as and for the purposes herein set forth.
